Original application filed July 20, 1909, Serial No. 510,484.

Specification of Letters Patent.

30, 1910. Serial No. 552,296.

To all whom it may concern:

Be it known that CARL ORGAARD, a citizen of the United States, residingat \Vheelock, county of illiams, and State of North Dakota, haveinvented certain new and use ful Improvements in Lamps, of which thefollowing is a specification.

This invention relates to lamps and more specifically to an improvedwick adjusting means therefor; the present application being a divisionof my application, Serial No. 510,484, filed July 20th, 1909.

The object of this invention is the provision in a lamp of improvedwiclcadjusting means which may be manipulated to readily and quicklyraise or lower the wick, means which will be of durable and economicalconstruction and efficient in operation.

Other objects will appear hereinafter.

With these objects in view my invention consists in an improvement inlamps characterized as above mentioned and in certain details ofconstruction and arrangement of parts all as will be hereinafter fullydescribed and particularly pointed out in the appended claims.

My invention will be more readily understood by reference to theaccompanying drawings forming a part of this specification, and inwhich,

Figure 1 is apartially sectional side elevation of a lantern equippedwith my improved lamp in its preferred form, F 2 is a slightly enlargedcentral longitudinal section of the wick-holding and adjusting meansembodied in my invention, Fig. 3 is an enlarged transverse section takenon substantially line a -a of Fig. 2, and Figs. 4 and 5 are details ofparts included in the wick-adjusting means illustrated in Figs. 2 and 3.

Referring now to the drawing 1 indicates the lantern casing, the detaildescription of which is found in the application above referred to, 2indicating the lens arranged in the front side of said casing and 3 thereflector mounted upon the rear wall thereof. Mounted in the base 4 ofthe casing, the same being preferably threaded therein, is an oil lamp5, the latter comprising a reservoir 6 and the tubular wick holder 7 8indicating the wick slidable within the latter.

Slidably mounted in the holder 7 is a snugly fitting sleeve 9 which isadapted to encircle and to carry said wick. Provided in said sleeve is atransversely disposed, preferably rectangular, slot 10 adapted toreceive the spike or pointed portion 11 of anormally curved member 12.In order to receive said spike portion and to permit of verticaladjustment thereof, the tube 7 is provided with an elongatelongitudinally extending slot 13. The spike 11 is of such a shape thatthe same will be received in the slot 11 only when the shank 12 thereofis in horizontally disposed position, the same being, when the latter isturned to vertically extending position, locked in position in thesleeve 9 because of the edge 14E of the latter engaging a recess 15provided at the base of said spike, as clearly shown in Fig. 2.

Removably secured upon the outer surface of the tube 7, by means offlanges 16 engaging the longitudinal edges thereof, is a longitudinallyextending channel member 17, the channel of which, when the latter isarranged upon said tube being in registering position with the slot 13of said tube. ith this provision, upon the wick being properlypositioned in the sleeve 9, the spike 11 of the member 12 is insertedthrough the slot 10 and locked in position in said sleeve in a mannerabove described. The wick is thus locked in position in said sleeve. Themember 16 is now positioned upon the tube 13 as before stated, in whichevent the shank 12' of the member 12 will rest in the channel thereof,said shank because of its resilient, normally curved condition forciblyengaging the upper edge of said member 17, as shown in Fig. 2. Byproviding the outer or contacting edge of said shankwith teeth, asshown, it is evident that the latter will engage said upper edge of saidmember, hence the sleeve 9 and consequently the wick 8 may be regulatedas desired and will be locked because of such teeth in any position towhich they may be adjusted.

\Vhile I have shown what I deem to be the preferable form of my device Ido not wish to be limited thereto as there might be various changes madein the details of construction and the arrangement of parts describedwithout departing from the spirit of the invention comprehended withinthe scope of the appended claims.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

1. In a lamp, a reservoir, a tubular wick.

holder having a vertical slot therein, a sleeve slidable in said holderand having a horizont ally elongated opening in the side thereofregistering with said slot, a spike shaped to be inserted through saidopening but to interlock with said sleeve when turned to anotherposition, a wick in said sleeve and an upwardly extending shankcarryingsaid spike, substantially as described.

2. In a lamp, a reservoir, a tubular wick holder having a vertical slottherein, a sleeve slidable in said holder and having a horizontallyelongated opening in the side thereof registering with said slot, aspike shaped to be inserted through said opening but to interlock withsaid sleeve when turned to another position, a wick in said sleeve, anupwardly extending shank carrying said spike, and a longitudinallyextending channel member removably secured to said wick holder andencompassing said shank, substantially as described.

3. In a lamp, a reservoir, a tubular wick holder, means for adjustingthe wick in said holder, said means comprising a sleeve encircling thewick and slidable in said holder, a pointed member passing through aslot in said sleeve and piercing said wick, means for locking saidpointed member in said sleeve, and a resilient toothed shank projectingfrom said pointed member, said holder being slotted for the reception ofsaid shank, a channel member arranged upon the outer surface of saidholder, the channel in said member being engaged by said shank, thetoothed side of said shank engaging the upper edge of said channeledmember to hold said sleeve in adjusted position in said holder,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CARL ORGAARD.
